MANIFOLDING APPARATUS.

Application tiled January 9, 1928, Serial No. 245,549, and in AustriaHatch 2, 19117.

This invention relates to an apparatus for manifolding in eneral andparticularly for duplicating boo eeping entries. A

A process is known for manifolding such entries, according to whichsimultaneously 4with the orifrinal entry a mirror or reversed .copythereofa is prepared, which is capable 'of giving oil' part of its coloror ink to an other paper and which is `'transferred line by line tocards or sheets by exerting a powerful pressure on the front face of thestencil. If before making the impression, the

cards are moistened, it is possible to obtain numerous clearly legiblecopies with a single stencil, but it is necessaryin that case to exert aconsiderable pressure in printing.

In spite of its advantages for bookkeeping purposes, this process hasnot been largely adopted in practice as up to now an .ap-

paratus did not exist which could be manipulated in a simple manner,manufactured at a small costv and yet would enable the work to be donequickly without too much effort.

The apparatus according to this invention solves this problem. Itsubstantially consists in a slide adjustable in the direction of heightof a bed or plate, which is formed into a device for clamping or fixingone longitudinal edge of the stencil, a moistening device slidablymounted in a cross-guide of the bed-plate and intended for moisteningthe sheet on which the manifold impression is produced, and a pressureor printing member, also movable in a cross-guide, for reproducing theimpression. The moistening device and the pressure or printing memberare preferably mounted on a fork, between the branches, or prongs ofwhich is placed the stencil, owing to which the moistening and theprinting may be effected in a single operation.

A construction according to the invention is illustrated by way ofexample in the ac companying drawings:

Figure 1 shows the apparatus in perspective.

Figure 2 is an elevation, partly sectional, of the most essentialelements 0f the lpparatus at an enlarged scale.

Figure 3 a cross-section according to the line 3--3of Figure 2 and Fi re 4 a sectional view of the line spacing evice.

1-is the base plate of the apparatus with 55 a bar or rai1'2 securededgewise thereto and a slidably mounted rail or slide 3, the distancebetween these two rails being equal to the width of the cards 4, onwhich the impressions are to be produced. 5 are two 60 marks indicatingthe distance of two lines for the purpose of facilitating thelineadjustment of the card.

The stencil 6- may for instance be made by means of a typewriter, carbonpaper be- 05 ing inserted so that its colorin side touches the back ofthe sheet, on which the types are striking, whereby simultaneously withthe writing on the front of this sheet a mirror or reversed copy of thiswriting is obtained on its back.

The slide 3 consists of two piirts lengthwise pivotally connected bymeans of hingejoints 7 and is slidably mounted in a uide 8 of the baseplate.` Between the sai two 75 parts of the slide, which in Figure 1 ofthe drawing are shown in the o en osition, the stencil 6 is to be fixed.or t is purpose the o ne part of the slide is preferably provided withpins 9 and the stencil with cor- 80 responding perforation. A linespacing device of known construction, as shown in Figure 4, may beprovided, which is operated by the handle 10 and which prevents theslide from being moved to fractions of the height of aline.

11 are guide rods, ixed to a head 12 and attheir other ends connected toone another by means of a frame 13 provided with a pres sure button 14.

The rods, or more exactly expressed their head 12, are journalled by ajoint 15 to a support 26 of the base plate, so that the `rods can turnup into an oblique position shown in Figure 1 under the action of a.spring 1.2* 95 placed underneath of the base plate and engaging with adownwardly extending part of the head 12.

The rods 11 are guiding the support 18 of the pressure roller 16, whichispressed down by springs 17. A rod 19 is secured parallel to the rods11 to the guiding body of the said roller support, is guided in theframe 13 and at its outer end provided with a handle 20. To the. lattera resilient (steel) band 21 is bodily connected or secured so as toextend inwardly parallel to the rods 11. This elastic band carries atits free end a wiper 22 of an absorbentr material for the moistening.The wiper is inserted in anl aperture ofthe bottom of a little tank orreceptacle 23, which is carried by the end of the band and can be closedup by a cover 24. For the purpose of maintaining the entire body of rodsandv band against the action of the spring 12a in the lowered position,the' lower part of the frame 13 may be held clamped by a screw 25.

The rod 19 carrying the pressure roller 16 I' and the resilient band 21carrying the wiper are thus forming a fork, between the branches orprongs of which is placed the stencil fastened to the slide 3 on its oneedge. By a suitable movement of the slide 3 the stencil is brought intosuch a position, that the pressure roller 16 is situated in the line tobe reproduced, The line vof the card 4, on which the entry is to becopied, is then set by means of the marks 5. The frame 13 is now presseddown, so that the roller 16 is pressed downward on the stencil,l whilstthe wiper 22 is in this position, owing to the re-f siliency of the band21, pressed against the card 4. If now by means of the handle 20 rollerand wiper are pulled along the guiding rods 11, the set line of the card4 is moistened and immediately thereafter the writing of the stencil 6is transferred to the card by the strong pressure of the springcontrolled roller following the wiper. When the roller has arrived atthe end of the line, the pressure on the frame 13 is released and thefork pushed'back, so that all parts will again be in the position asshown in Fig. 1. The card 4 is thereupon replaced by another one, onwhich the same entry is to be made.

VIn the .operation of printing it may happen, that the roller 16 runs tothe edge of the kstencil and the wiper 22 is moved beyond the edge ofthe card 4. The stencil will ythus not be'supported anymore by the band21 and for 4moving the printing device back .into its original positionit should be necessary to re-introduce it between the roller 16 and theband 21. In order to avoid such necessity needle-like little rodsorrails 28 are secured to the frame 13, which are supporting the stencilalso in the case of the wiper trespassing the edge of the card.

For the purpose of making the already transferred lines of the stencil,there may be provided adjustable needles 27 on the support26, tov whichthe head 12 is journalled. wWhen the latter is pressed down, theseneedles are by the action of a plate lowered and will be driven ythroughthe stencil, the

with suitable spaced holes 32 lof the base part of the slide 3 and atits rear end it is by means of a link 33 connected to the handle 10, bywhich the line spacing device is actuated.

The apparatus according to this invention is particularly adapted forlmanifolding line by line, it may, however, also be used as ordinaryduplicating apparatus reproducing the writing on kthe entire surface ofthe stencil in one operation, For this purpose itis only necessary tomake the length of the roller 16 and of the wiper equal to the heightofthe stencil.
